(X) = Stone largely consists of this size
(..) = Stone can consist of up to 15% of this size
(.) = Stone can consist of up to 10% of this size
**Each stone gradation can contain up to 10% upper and lower grades and some fine material (sand).

In the upper range of our stone sizing -- 4" down to 2"
This covers products such as #1 Stone, Large Beach Pebbles, and Red Rock. Their weight makes them a sturdy and excellent decorative stone, especially for creating borders and outlining gardens and driveways.

In the mid range of our stone sizing -- 2" down to 1/2"
This covers products such as Granite and Limestone Gravel, along with River Rock and Recycled Crushed Concrete -- all excellent choices for driveways, with similar functional properties and differing aesthetics.

In the lower range of our stone sizing -- 1/2" down to fines (industry term for sand, stone dust and tiny particles):
Products in this range are notably more compactible and suited for creating a base layer -- products such as Crushed Limerock, Screenings, Sand and Soil.

For support of heavy vehicles -- choose our #1 or #4 stone
For standard driveways -- choose our #57
For more decorative driveways -- choose our 1/2" to 2" river rock
For driveways / paths more comfortable to walk upon -- choose our #89
